Letters l'ateat No. 95,206, dated September 28, i869.

4 coAL-srovs.

l The Schedule referred to in` these Letters Patent and making part of the same.

.Be it known that u I, RICHARD S. DILLON, `of Dei troit, in the county of Wayne, and State of Michigan,

have invented a new andnseful Improvement in Heating-Apparatuspand I do declare that the following is atrue and accurate description thereof, reference being had to 4,the accompanying drawings, and to the letters -of reference marked thereon, and being a part of this specification. v i

s The drawing is a vertical section of my invention,

y the nature of which relates to au improvement in the construction of stoves and tiu'nacesfor heating-purposes, wherein all the particles of carbon, smoke, and

gases liberated in the combustion of coal may be enlt'uelyconsumed, said device being best adapted to the economical consumption of bituminous coal.

l 'lhc invention consists in the arrangement, within the shell of the stove, of 'a reverberatory chamber, in which the combustion commenced in the {ire-chamber is completed by the admixture of air, in suitable proportions, with `the gases, at `proper points .in said chamber, so that the entire products of combustionshall be consumed within the stove, thereby utilizing all of the heating-properties of the coal. It also consists in a peculiar arrangement of an air-` y chamber and tubes, for delivering `atmospheric airv to l the reverberatory chamber, and in the'general arrangement of all the parts.

A'represents the cylindrical body of my improved stove, terminatingin a contracted neck, A.

l i The 'stove is fitted with a chute, B, through which ,the fire is replenished with fuel when necessary.

It is also providedwith `the usual grate, draughtdoor, and ash-pari. l i

Surrounding theneck of the stove is an air-chamber, C, provided with registers,`c, through which air may be admitted to the interior of the chamber. A i The air is `brokenV into minute jets, by being compelled to. pass through .a perforated diaphragm, AE,

which is placed within the chamber. A Surmounting theiwalls of theair-chamber is an annular conical iiange, 1 ),whose inner periphery turns up'and-terminates at the level ofthe top of the neck. A of the stove, leavingan` annular air-space between it andthe neck.

Surxnounting theiiange D, and il: nged on` its innerl w periphery, is a ilue, F, having an encircling deflectiugiiange, f, atitstop. y y f i The material of which this lue is constrnctedis-ire- `brick`,"or fire-clay, or other heat-retainin g and radiating 1 f material; i

G are air-tubes',` risingfrom the air-chamber, and support a gasering, H, in which their upper ends ter- I is a reverberatingchamber, closedl at the top, and

stove and radiator-case.

resting, by its flange t', onthe gas-ring H, leaving an annular space between the ange 'i and the exterior ofthe flange D. l

The reverberating-chamber I is constructed of the i same refracting-material` as `the due F, and its arch or crown, I', may bet strapped with iron to strengthen it Surrounding the reverberatory chamberl is aradiai tor, J, which may be of sheet or cast-1netal, and is provided with an outlet, j, at the top, to which a properppe is attached to maintain the draught.

The operation of this improvement is as follows: A suitable fire is made in the body of the stove. As soon as the walls of the flue F fand chamber d be- .come highly heated, from the passage lof the flame and gases in contact with them, the registers c are opened, and a supply of oxygen is admitted to the airchamber G, passing through the perforated diaphragm E, when it is subdivided into numerous small jets,

and rising through theV annular spaces between the neck and flange, comes into contact with `the products of combustion, with which it mixes, and causes them to ignite;

The flames pass up to the crown of the reverberad tory chamberywheu the. draught will bring them around the iiangc j' of the flue, and down into the space between theilue and outer walls of the chamber.

ample room to mix with the gases and ignitethem,

:the admixture being promoted bythe currents being retarded bythe-.flange f, which serves as a bridge- Y wall, breaking up the currents.

The currents then pass down betweenthe flange y of the chamber and the base ofthe due, and the dames receive a fresh but limited supply of air through the air-tubes Gand gas-ring H, under the'lange; and as they pass up between the outer walls of the reverberatory'chamber and the radiator J, should there be any unconsumed particles of carbon in the current, or nnignited gases, they are ignited and totally consumed, perfect combustion. being the result, and the greatest possible amount of ,heat radiated from the p The wallsV of the iuevand revcrberatory chamber being'heated to a high degree, small particles of unconsumed carbon readily ignite from the heat radiated from said walls and chamber, combustion being promoted -by bringing a fresh supply of oxygen into contact with them, in the manner described..`

`Ihe perforated `diaphragm-plate E also serves to make thesnpply of air even in its current totheiiamc. What I claim as my invention, and desire to secure by Lcttcrs'Patent, is-

` l. The arrangement of the annular air-chamber C The enlarged area of thisspace gives the oxygen provided with registers c, the conical deiiector-ange D, air-tubes G, and gas-ring H, with or without the perforated diaphragm E, substantially as herein specitied, and for the purpose mentioned.

2. The fue F, provided at its top with the outwardprojecting flange f and the reverberatory chamber I, provided with laninternal ange, z', arranged within a radiator, J, substantially as and for the purpose herein set forth.

3. The arrangement of the foregoing-named parts with the body A of a stove or furnace, having a contracted neck, A, when coustrueted, combined, and operating substantially as and for the purposes herein described.
